There is a widely held but quite erroneous belief that figurative painting, is not found in Islamic art due to prohibition by the Koran. Religious rulings issued only in the ninth century discouraged the representation of any living beings capable of movement but they were not rigidly enforced until the fifteenth century. Figural art is especially rich in tiles as well as stone and stucco reliefs of the Seljuk period, adorning both secular and religious reliefs monuments. The subjects included nobility as well as servants, hunters and hunting animals, trees, birds, sphinxes, lions, sirens, dragons and double-headed eagles.
